A Juneau man faces a rare DUI charge for allegedly having a 0.313 breath-alcohol content as he floated through Fairbanks on an inflatable raft Sunday night.

Alaska’s driving under the influence law applies to people operating motor vehicles, water craft and airplanes. The vast majority of charges are for terrestrial motor vehicles.

But when Alaska State Troopers received a report of a “heavily intoxicated” man floating down the Chena River near the Parks Highway bridge at 6:40 p.m. Sunday, a wildlife trooper boat responded and arrested 32-year-old William Modene.
